• Description : SILOGRID is a robust and reliable wireless network, designed for industrial disturbed environments

witch are creating interference that may significantly degrade network performance. Silogrid is based on a proven wireless meshed network technology - SmartMesh ® Dust Networks ®, it uses the 2.4 GHz unlicensed band as a transmission medium. Silogrid relies on a mesh network in which all radio stations (silo sensors) form the network. Each involved station simultaneously serves as a source signal and as a repeater. The original transmitter sends a message to its nearest neighbor, which transmits it in its turn until the message reaches the final receiver station (the manager). Furthermore, alternative paths are defined in the initialization phase. If the message can not be transmitted on a particu-lar path, for example due to an obstacle or a defective receiver, the message is automatically deflected onto an alternate path. Thus, in addition to extending the range of the network, the mesh network provides redundant communication paths to improve reliability. The communication of the wireless network is coordinated by a TDMA system (Time Division Multiple Access) that syn-chronizes the networks involved by time blocks of 10 ms. This creates a very reliable network (without collision) and re-duces the time that a station must be active. To avoid interference, Silogrid also uses FHSS (Frequency Hopping Spread Spectrum ). The 15 channels defined in the IEEE802.15.4 standard are used in parallel, Silogrid uses FHSS to make the jump be-tween channels. Channels in use are put on a "black" list to avoid collisions with other wireless communication systems. The combination of the synchronization every 10 ms and the 15 channels, allows up to 1500 communications per sec-ond.

Silogrid: Radiofrequency temperature meshed network measuring

system for silo thermometry applications

A broken path (disturbance) is automatically replaced by another.

8 possible jumps up to the receiver.

Each node is a router, it can transmit and receive.

In a SmartMesh network, each node is a router that can communi-cate with any other node within range. The network dynamically identifies the paths in the mesh based on the constant monitoring of the network and radio fre-quency environment. It creates all redundant routes through the mesh and maintains multiple paths for each node. It detects and reassigns the broken paths.

The TNL120 is an autonomous and waterproof temperature acquisition station, capable to broadcast the meas-urements by radio link. It can be used both for new installations or as retrofit. The station is not dedicated to a particular type of sensor, but configurable depending on the installation.

Description:

Each TNL120 form a network node. The network nodes are ultra low power wireless transceivers, which sends data from temperature sensors, and transfers the data packets of neighboring nodes. Each node transmits packets to other nodes in a series of jumps that provide data to their destination. Preconfigured nodes can be added or removed from the network without disturbing the communications, creating a highly flexible and scalable system. Configurable measure inputs: - up to 24 PT1000 or NTC / PTC inputs in 2-wire with common point.

The SML160 is a wireless receiver with an Ethernet connection, the product centralizes all measures issued by the radio transmitters, and makes them available through a standard communication protocol (Modbus-TCP) on the Ethernet link.

DESCRIPTION: The hub is an integral part of the wireless mesh network, It coordinates the routing of data packets, collects measurements, network statistics and manages all data transfers, information are accessible by Ethernet on a dedicated web page.

Operating mode: - Two operating modes are possible: 1) "installation" mode, while within range transmitters automatically join the network and declare themselves in the equipment list of the site. 2) "operation" mode, while only transmitters declared in the list may join the network. (possibility to have several network on same time on a wide site). The operation mode can be changed after the commissioning. Each transmitter has a unique MAC address. - The receiver's webpage is useful to see the measures, the network statis-tics (number of jump, signal quality, battery voltage) and the configuration of the network transmitters (tag, number of T° points)

Realization: - projecting wall mount (hinged screw cover). - Waterproof ABS plastic housing + conformal coated electronic IP66 protection rating, cable gland entry

- Power supply over Ethernet (PoE).

Front face: Three LEDs for a rapid diagnostic . - One power ok blue LED. - One "default" red LED, indicating the absence of a transmitter, a defect temperature point or a weak transmitter battery voltage. - One "ok" green LED Indicating that the installation operates according to the configuration defined for the site.

Configuration: IP address: 2 solutions are possible 1) via BOOTP protocol by entering the MAC address found on the inside of the product (requires a BOOTP server on the network) 2) Fixed IP address, configured via the embedded Web server. If the IP address is unknown, an internal button is used to return to the factory IP address: 192.168.0.253 (long press, the buzzer confirms the return to the original address).
